Bridges that require concrete decks to be poured post precast erection will need to have forming onsite for casting. Precast/Prestressed bridge girders can include blockouts, embedded inserts, embedded pipe for automated screed machines and other miscellanist items to help secure contractor provided formwork to girder. Often (we coordinated with precaster) formwork can be installed prior to installation for exterior girders to allow faster construction.
Prestress/precast concrete members are the choice material for the superstructure of bridges in the Pacific Northwest. The extended service life, low maintenance, low permeability (rust protection), and quality of these components make them the obvious choice for bridge design. Prestress/precast superstructures improve quality by using plant-controlled manufacturing and increase safety at the job site by accelerating construction schedules. Minimizing road closures is important in the planning and construction of a bridge, and this can be achieved with the use of our superstructures. Whether your bridge span is 20′ or 200′, Knife River and our skilled delivery partners can help facilitate your project from concept and fabrication to delivery with safety, quality, and efficiency as our priorities.
